' ing-pipe and communicating with the outside atmosphere, whereby a draft or current is formed, and a means for spraying-and keepingwet the outer surfaces of the chambers and zoafter fullyexplaiu.

The object of my invention is to provide a water-cooler of simple construction and efl'ective operation. f

Referring to the accompanying drawings, 2 5 Figure '1 is an elevation of my water-cooler and a vertical section of the jacket surrounding it. Fig. 2 is a horizontal sectionof' the upper compartment, A, on an enlarged scale. Fig. 3 is a vertical section of the water-cooler. Fig. 4is a horizontal section of the lower compartment, O. I

A is a water-chamber, provided with a top,

- a, either permanent or removable, as the case may be, whether the chamber is supplied by a hydrant-pipe, B, as herein shown, or by actually filling it with water from buckets.

Gis asecond chamber, underthe first. Both of these chambers are wrapped upon their outer surfaces with woolen or other such absorbent fabric, 1), Fig. 3.

D is the pipe which connects the two chambers. ,It opens out from the bottom of chan1= her A, and follows a vertical,tortuous, or winding course over the outer circumference of chamber 0, and then a spiral course around its vertical portions until it enters chamber 0, near its bottom. i

The object in thus causing the pipe 1) to follow such a tortuous course is to obtain as much length of pipe as possible and expose as much surface, wherebyahe water, in passing from connecting-pipe, all of which I' shallhereinnecessary I could use fans and other blast or one chamberto'the other, may have time to be 'fully subjected to the cooling influences hereinafter described; Thispipe Dis wrapped with woolen orother fabric, (1, throughout its entire length, Fig. '3.

Opening out from the upper chamber, A, is a pipe, E, which passes around the outer circumference' of the chamber, and is'prov'ided with. small holes cover its extent, whereby a fine spray or shower maybe made to fall about the outside of the chambers and the conneeti ing-pipe. j

F is an outer casing, of larger diameter than the chambers, and covering them both, leaving an airspace, f, between them and the outer casing. The chambers are secured in the easing by braces c, as shown. I

G is the faucet, which taps the lower chamber," O, and extends across the air-space and 0 through the outercasing.

G is a tap, by which the sediment is drained.

My object is to connect the airspace f'with the atmosphere wherever it is likely to be the coolest. This may be done, as I have here shown, by a pipe, F, fitted to the bottom of casing Fand communicating with an aperture inthe floor H, and above bya pipeg lr fitting the top of the casing and extending through the roof R of the building or apartment. This opens up'an air-passage, which creates a draft I of coolair about the water-chambers and pipe connection, which, together with the constant shower of spray, keeping the wrapped exteriors of chambers and pipe wet-{serves to cool 8 5 the water'efi'ectually.

In order to turn off the spray when desired, I have a cock, Z, in the spray-pipe. In this way I may keep the wrappin gs about half wet, which I find gives very good results. This double connection with the outer atmosphere provides for the draft or current either way, whether the.wind be up or down.

I need not confine myself to making the connection of the air-space f with the outer atmosphere through the floor and roof, but may, according to localities and by proper elbows and joints, make the connection through the walls or through windows or doors; and if draft producing or inducing devices to make the current through the air-space. This draft 9 ceases circulates freely about the exterior ofthe chambers and the pi pe-connection,which latter, presenting so large a surface to the draft, is well cooled, and its attenuated body of water is similarly affected. The spray adds to this effect very materially, and by keeping the-wrappings saturated presents material for rapid evaporations, and the consequent lowering of the temperature. i

If the upper chamber, A, should have to be supplied with water fronrbuckets directly, a hinged door could be made in the outer casing to afford access to the removable cover 0.

Having thus described my invention, what I l 5 claim as new, and desire to secure by Letters Patent, is- 1 1. In a water-coolcr, a double-compartment water-chamber, onecompart-ment being provided with an inlet and the other with an outlet, and an outside pipe-connection between the -two compartments, in combination with an inelosing-easing over said chamber forming an air-space or jacket surrounding the chamber and connecting-pipe, said air-space communicating with the outside. atmosphere, whereby a draft or current of air is formed and circulates aboutthe exterior of said cha-mher and connecting-pipe, substantially as herein described.

2. In awat-er-cooler, a double-compartment water-chamber, one compartment being provided with an inlet and the other with an outlet, and an outside'pipe-connection between the two compartments, in combination with an outer casing covering said chamber and forming an air-space surrounding the chamber and connecting-pipe, and a spray-pipe connected with'one water-compartment and discharging within the surrounding air-space, substantially as and for the purpose herein described.

3. In a water-cooler. a double-compartment water-chamber, one compartment beingprovided with an inlet and the other with an outlet, and an outside pipe-connecti on between the two compartments, in combination with an outer casing coveringsaidchambeaforming an aire, space surrounding the chamber and connecting-pipe, said air-space communicating with 50 the outside atmosphere, whereby a draft or current of air is formed and circulates about the chamber and connecting-pipe, and a spraypipe connected with one water-compartment and discharging within the surrounding airspace, substantiallyas and for the purpose herein described. 4. In awater-cooler, the chamberA, having a water connection or inlet, and the chamber 0, having o'utlet G, in combination with the connecting-pipe D, opening from vchamber A, and wound about, around, and upon thb exterior of chamber 0, and discharging therein, substantially as herein described.

5. p In a water-cooler, the chamber A, having a water connection or inlet, the chamber 0, having outlet G, and the connecting-pipe D, opening from chamber A, and wound about,

7 around, and upon the exterior of chamber 0,

in combination with the outer casing, F, forming air-s'pacef, the pipe F, through the floor, andth'e pipe F through the roof, whereby said air-space is connected with the outside atmosphere, substantially as, and for the purpose herein described.

.6. In a water-cooler, the chamberA, having I a water connection or inlet, the chamber C,

having outlet G, and the tortuous pipe D on the exterior of chamber 0, connecting the two chambers, in combination with the outer casing,F,forming air-space f, the pipe F, through the floor, and the pipe F through the roof,

.and the annular perforated spray-pipe E, opening from chamber-A and discharging within air-space f, substantially as and for the purpose herein described.

7 In a water-cooler, the chambers A C and tortuous connecting-pipe D, said. chambers and pipe being wrapped with woolen or absorbent fabric b d, in combination with the outer casing, F, forming air-space, f, said air-space communicating with the outside atmosphere, and the spray-pipe E, for keeping wet the wrappings of the chambers and pipe D, sub-. stantially as herein described.

In witness whereof I have hereunto set my hand.
